Russ Cox dfa5893d4f preparation for exec.
* syscall:
	add syscall.RawSyscall, which doesn't use sys.entersyscall/sys.exitsyscall
	add syscall.dup2
	add syscall.BytePtrPtr
	add syscall.Rusage, RusagePtr
	add syscall.F_GETFD, F_SETFD, FD_CLOEXEC

* runtime:
	clean up, correct signal handling.
	can now survive (continue running after) a signal.

Russ Cox 96824000ed * comment, clean up scheduler
* rewrite lock implementation to be correct
  (tip: never assume that an algorithm you found
  in a linux man page is correct.)
* delete unneeded void* arg from clone fn
* replace Rendez with Note
* comment mal better
* use 6c -w, fix warnings
* mark all assembly functions 7

Russ Cox d28acc42ec first cut at multithreading. works on Linux.
* kick off new os procs (machs) as needed
* add sys·sleep for testing
* add Lock, Rendez
* properly lock mal, sys·newproc, scheduler
* linux syscall arg #4 is in R10, not CX
* chans are not multithread-safe yet
* multithreading disabled by default;
  set $gomaxprocs=2 (or 1000) to turn it on

This should build on OS X but may not.
Rob and I will fix soon after submitting.
